DNA & Sports Performance: Born Marathoner or Sprinter?

Running has become a global phenomenon — from 5K joggers to ultra-marathoners, people everywhere are embracing movement. But one question keeps coming up: are we born to sprint or to endure?

The genetics of speed and endurance

Science has identified key genes that influence athletic performance. One of the most studied is ACTN3, which produces a protein found in fast-twitch muscle fibers — the kind that power sprints and explosive movements.

Individuals with an active ACTN3 variant tend to excel in power and speed sports.
Those with an inactive variant often show better muscle efficiency and endurance, ideal for long-distance events.

Other genes also play a role:

• ACE: influences cardiovascular capacity and blood flow;
• Genes linked to fatigue resistance, recovery, and oxidative stress.

Running: a biological and cultural passion

Humans are literally built to run. Our body’s cooling system, posture, and muscles evolved for endurance — but today, running means much more. It’s about health, balance, and joy.

A sports DNA test doesn’t tell you what you can’t do; it helps you understand how your body performs best — how you recover, adapt, and stay injury-free.

Nature meets training

DNA provides the blueprint — but training writes the story.
A genetic predisposition to sprinting or endurance means little without consistent effort, rest, and nutrition. Performance is always a blend of genes, environment, and mindset.

At Adnà, our Sports & Wellness DNA Tests help you understand how your body responds to effort, recovery, and nutrition — so you can train smarter, not harder.

Because between a sprinter and a marathoner, there’s no “better” athlete — only a better understanding of yourself.
Your DNA has answers.
